EMBosslNG-MACHINE.

SPECIFICATION forming' part of Letters Patent No, 709,422, datedSeptember 16, 1902. Application filed January 3,1201. Serial No. 41,995.(No model.)

To all whom t may concern: i

Be itknown thatLFRnNK KEACH RUSSELL,

a citizen of the United States, residing at Dallas, inthe county ofDallas and State of Texas, have invented certain new and usefulImprovements in Embossing-Machines; and I do declare the following to bea full, clear, and exact description of the invention, such as willenableothers skilled in the art towhich it appertains to make and usethe-same.

The invention relates to1 embossingmachinos, aud more particularly tothose used by saddle-makers for stamping leather.

The object of the invention isto provide a machine of the characterAdescribed whereinv the impression-rolls are mounted in a novel manner,so that shorter curves may be embossed without the dragging or tearingeffect tional view through the same.

common with the usual means now in use.

A further object is kto provide a machine of this character which shallbe simple of construct-ion, durable inuse, and comparatively inexpensiveof production.

To these ends the invention consists in the features of construction`and novel combination and arrangement of parts hereinafterdescribed,'and then more particularly set forth in the claims followingthis specification.

In the accompanying drawings, Figure 1 is a side view of my improvedembossing-machine. Fig. 2 is a vertical longitudinal secf detail view,on an enlarged scale, showing the relative arrangement of one of therolling gear.

shafts, its gear, and the crank and its mesh- Fig. 4 is a sectional viewtaken on the line :t of Fig. 1. Fig. 5 is a detail sectional Viewthrough one of the impressionrolls and its shaft. y

Referring now more particularly to the drawings, 1 denotes the frame ofthe machine, which may be a casting of any desired shape orconfiguration; 2, the throat of the machine; 3, the upper set of`bearings of the upper rollshaft; 4, the lower set of bearings of thelower roll-shaft; 5, the upper roll-shaft, and 6 the lower roll-shaft.The upper roll-shaft 5 has mounted on its forwardend a series ofimpression-rolls 7 and 7, which may be of any desired number and thesurfaces of which may be provided with any form of design orconfiguration. The center roll 7 of the series Fig. 3 is a vent anyundue tearing or dragging of the material when working around shortcurves ,or turns in the same, which would be the case if the rolls wereall positively driven.

The lower roll-shaft has fixed upon its forward end a wide bearing-roll7b, which coacts with the upper feed-roll 7 and also presses thematerial against the upper series of impressionrolls. 'The rear end ofthe roll-shaft 5 has 'fixed to it a bevel gear-wheel 8 and a plaingear-wheel 9, while the rear roll-shaft 6 has fixed to it a plain gear10, which meshes with the gear 9 on the shaft 5. Y

11 denotes a bearing fixed to the rear end of the supporting-frame, and12 denotes a crank-shaft journaled in said bearing andprojectingrearwardly and arranged atan angle of about onehundred andfive degrees to the shafts 5 and 6 and provided with a gearpinion 13, inmesh with thegear-wheel S of the shaft 5. The crank may be provided withan operating-handle 14. It will be noticed that by the rotation of saidcrank motion will be imparted to the shafts 5 and 6, and as the rollsare fixed to said shafts they will operate upon the material in theusual manner. `The main feature of this part of my invention is thearrangement of the crank-shaft 12 at an obtuse angle to the shafts 5 and6, whereby said shafts may be more conveniently rotated than if thecrank were secured directly to the end of one of said shafts. i

Another feature of my invention resides in the manner of forcing oneofthe rolls toward the other roll in working on leather or metal. To thisend I mount the rear end ofthe shaft 6 in a bearing 15, which willpermit of a slight rocking movement of said shaft at its rear end. Theforward end of the shaftis mounted in a bearing-box 16, supported tohave a veI'-,

A treadle or lever 19 is fixed to la lug 19', depending from the frame,and has a bill 20, which is adapted to engage a pin 21, extendingdownwardly from the box 16 and designed when the treadle or lever isactuated in one direction to elevate saidl bearing-box 16, and thusforce the lower roll toward the upper roll. When the pressure is removedfrom the lever or treadle, the lower roll drops to its normal position.It is of course understood that while the movement of the forward end ofthe shaft 6 is sufficient to accomplish the desired result the movementof the rear end of lthe shaft is so slight as not to disengage the teethof the gear-wheel 10 from the teeth of the gear-wheel 9 on the shaft 5.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and mode of operation of myimproved embossing-machine will be readily understood without amoreextended explanation ofthe same.

Various changes inthe form, proportion, and minor details o'fconstruction may be made within the scope of the invention withoutdeparting from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to securevby Letters Par.- ent, is-

1. In a machine of the character described, the combination of upper andlower geared roll-shafts and means forl rotating the same, of a series0E impression-rolls mounted upon said upper roll-shaft, the center oneof which being xedly mounted thereon and the rest loosely mountedthereon, a bearing or pressure roll fixed on said lower roll-shaft andadapted to bear upon said impression-rolls, and means for regulating thepressure of said bearing or pressure roll, substantially as and for thepurpose described.

2. In anembossing-machine provided with a suitable frame and upper andlower geared roll-shafts mounted therein; a series of impression-rollsmounted upon said upper rollshaft, the center one of which being fixedlymounted thereon and the rest loosely mounted thereon whereby in makingcurved figures upon leather or other material the roll or rolls betweenthe center of the figures or impressions and `said xed roll will bepermitted to run slower than the fixed roll and the roll or rollsoutside of the fixed roll will be permitted to run faster than Ysaidfixed roll, a suitable bearing mounted on the lower roll-shaft, andmeans for operating the machine.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- TIBSSGS.
